SPARK-ARRESTER.

SPECIFICATION forming part of Letters Patent N0.392,672, dated November 13, 1888 Application filed August 10, 1888.

To all whom it may concern:

Be it known that I, CHARLES M. GARRISON, a citizen of the United States, residing at Wichita, in the county of Sedgwick and State of Kansas,have invented certain new and useful Improvementsin Spark-Arresters; and I do hereby declare that the following is a full, clear, and exact description of the invention, which will enable others skilled in the art to which it appertains to make and use the same.

This invention relates to smoke stacks and conveyors for locomotives; and its object is to provide a device of this character whereby the smoke is driven through a pipe or conveyer and back into the firebox or to the ground.

A further object of the invention is to provide the pipe or conveyerwitha condenser for condensing the smoke, extinguishing sparks, and collecting dust, 850., during its passage thcrethrough.

A further object of the invention is to provide a smoke stack and condenser possessing advantages in point of simplicity, inexpensiveness, durability, and general efficiency.

In the drawings, Figure l is a side elevation of a smoke stack and conveyor embodying my invention. Fig. 2 is a longitudinal Fig. 3 is a similar viewtaken at right angles thereto. Fig. (L is a front elevation. Fig. 5 is a transverse sectional View.

Corresponding parts in the figures are denoted by the same letters of reference.

Referring to the drawings, A designates the stack proper, terminating at its upper end into two angular or semicircular pipes, 13 B, having their ends I) b opposing each other.

C designates a cylindrical casing disposed vertically between the ends of the pipes B and provided at opposite sides with central openings, c 0, over which said ends are secured.

\Vithin the casing G is disposed a fan, D, comprising a shaft, D, journaled in suitable bearings, d d, at each side the casing. One end of the shaft is extended through one of the pipes B, and is there preferably provided with a pulley, d, designed to be connected with the machinery of the locomotive by a belt for imparting motion to the fan. The

pulley d is preferabl rovided wi th a ratchet,

(1 as shown, to prevent reverse motion of the fan when the locomotive is backed. From the shaft D within the casing extends a series of radial wings, D, which conform in shape to the casing and fit closely therein.

E designates a pipe or conveyer, which opens at its forward end into the casing at the upper rear edge of the latter, as shown at c, and at its rear end into the firebox of the locomotive, or extended to near the ground, as desired or found preferable. This pipe is provided near its point of connection with the casing with an approximately U shaped bend,

E, having at its lower end a removable plug, F, or other suitable device for permitting the discharge of the contents, and at one of its upper ends with a similar plug, F, for filling said bend. The bend E is designed to be filled with a suitable substance-such as salt brinefor condensing the smoke and extinguishing the sparks as they pass through the pipe.

The operation and advantages of my invention will be readily understood by those skilled in the art to which it appertains. The smoke enters the casing at its center from each side through the pipes 13 B as the fan revolves through the medium of thelocoinotive machinery. The smoke is driven by centrifugal force to the outer ends of the compartments formed by the wings of the fan, and as each 01' said compartments comes opposite the pipe E the smoke is driven into and through the same back to the fire-box or to the ground. During the passage of the smoke through the contents of the Ushaped bend the same is condensed, the sparks extinguished, and the dust, &c., collected.

It will be obvious that my invention can be equally as well applied to stationary engines; and, further, 1 do not wish to be understood as limiting myself to the exact construction herein shown and described, but reserve to myself the right to all such modifications as properly fall within the spirit and scope of my invention.

I claim as my invention 1. The combination, with a locomotive smoke-stack bifurcated at its upper end, of a cylindrical casing disposed between the pipes formed thereby, said pipes opening centrally within the casing, a rotatable fan journaled in said casing, and a conveyer opening into the opening for respectively filling or emptying upper portion of the casing andhavingabend the same, substantially as and for the puradapted for the reception of a eondensingmapose set forth. terial, substantially as set forth. In testimony whereof I affix my signature in 5 2. The combination, in alocomotive smokepresence of two witnesses.
